Projects Synthesis Materials Fabrication Devices Characterization Theory
This year we have nearly 30 projects covering a wide range of nanoscience, including facile synthesis of organic and inorganic nanowires and nanostructures, novel fabrication routes, building of functional bioarchitectures, nanostructured devices and nanowire applications. Please browse the menu (hover on a group and click on the project of choice) to view brief overviews of our projects.
Vanadium Dioxide (VO2) Based Thermoelectric Device
One-dimensional (1D) nanomaterials continue to be of considerable interest for their potential use as building blocks of functional nanoscale devices as they exhibit significantly different properties compared with their bulk counterparts due to surface effects and unique dimensionality. We are particularly interested in VO2 nanowires that show interesting metal insulator transition at a relatively easily accessible transition temperature, i.e. ~ 680C in bulk. We will attempt to exploit its thermoelectric property to realize high performance thermoelectric devices.
